[appengine-java] RPC SerializationException if detachable=true

[Patrizio Munzi]

Hi all, a strange thing happens when I try to serialize via RPC a list of PersitentCapable objects after having called detachCopyAll(). If the PersistentCapable objects have the property detachable=true the serialization throw the following exception. Instead if the property detachable=true isn't set everything works fine. Do you have any idea what's the problem???
